What's the Maximum Number of Cards in a LinkedIn Carousel Ad?

A LinkedIn Carousel ad requires a minimum of 2 cards and allows a maximum of 10, per LinkedIn's official Carousel Ads advertising specifications.

Per-Card Image Requirements

Each card accepts an image up to 4320 x 4320 pixels, with a maximum file size of 10 MB. LinkedIn's recommended spec is a simpler 1080 x 1080px square at a 1:1 aspect ratio, in JPG, PNG, or non-animated GIF format. Headline text on each card is limited to roughly two lines before LinkedIn truncates it, which in practice means keeping individual card headlines short and front-loaded with the key word or phrase.

Shared Ad-Level Text

Unlike the per-card headline, introductory text sits above the whole carousel and is shared across all cards. LinkedIn allows up to 255 characters here, but recommends staying under 150 to avoid truncation on some devices and placements. Destination URLs for each card can run up to 2,000 characters, though the visible call-to-action text tied to that URL is capped at 45 characters per card.

You Can't Edit Cards After Saving

One structural quirk worth planning around: once a LinkedIn Carousel ad is saved, its individual cards can't be edited afterward. Any change to an image, headline, or destination link on an existing card requires building a new carousel ad rather than revising the one already running, which makes it worth double-checking every card before publishing rather than treating the format as something to tweak after launch.

How This Compares to Meta's Carousel Format

LinkedIn's 2-to-10 card range matches Meta's Facebook and Instagram carousel ads exactly, which makes the format easier to port between the two platforms without redesigning the card count. The platforms diverge more on text limits: LinkedIn's per-card headline runs by line-wrap rather than a hard character number, while Meta sets a flat 40-character cap, so creative built for one platform's carousel still needs a text pass before reuse on the other.

When to Use Fewer Than 10

B2B advertisers most often use LinkedIn Carousel ads to walk through a short, sequential story, such as product features, case study steps, or a multi-part offer, and 10 cards is rarely necessary for that kind of narrative. A carousel that uses most of its 10-card ceiling without a clear reason for each card tends to lose viewers partway through the swipe, so the card count is worth matching to how many genuinely distinct points the ad actually needs to make.

Bottom Line

Build LinkedIn Carousel ads with at least 2 cards to use the format at all, keep the count closer to 3 to 6 unless the message genuinely needs more, and review every card carefully before saving since none of them can be edited afterward.

The Ad's Internal Name Has Its Own Limit

The ad's own internal name, visible only to the advertiser inside Campaign Manager and never shown to the audience, can run up to 255 characters as well, useful for labeling which product line or test variant a given carousel belongs to.
